Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a road surface metal anti-cracking net quick anchoring device. Background Art

[0002] The main disease of asphalt and cement concrete pavements of highways is the damage of the reflective cracks in the pavement base layer to the pavement surface structure, which leads to early damage to the pavement, increases the cost of maintenance and repair, affects driving safety and comfort, and even reduces the service life of the highway. The reason is that the design requirements of the base layer and the surface layer are different, and the materials used are also inconsistent. Under the influence of the atmospheric environment and vehicle loads, the upper and lower structural layers bear different forces, which leads to the generation of pavement cracks. In order to eliminate or reduce the generation of early cracks in the pavement, engineering and technical personnel have studied a metal anti-crack net in production practice for paving on the base layer of the pavement, and then pouring asphalt concrete pavement on it. The effect of preventing cracks is very obvious.

[0003] The metal anti-crack net is composed of several hexagons. The vertical sides of two adjacent hexagons are twisted together to form a twisted part, and two first oblique sides are formed above the twisted part, and two second oblique sides are formed below the twisted part. Since the road metal anti-crack net is a silk material with high tensile and compressive strength, it was previously necessary to use manual hammers to hammer steel nails into the base to anchor the metal anti-crack net. The anchoring spacing is small and the density is high, the labor intensity of manual work is high, and the work efficiency is low. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a quick anchoring device for metal anti-cracking net on a pavement, including a gas gun, a nail and an anchor plate, the anchor plate is used to cover the twisted part, two first oblique sides and two second oblique sides of the metal anti-cracking net, the lower end face of the anchor plate is connected to a limiting member, the limiting member is used to abut against the two first oblique sides or the two second oblique sides, the upper end face of the anchor plate is provided with at least two depressions, the projection of each depression in the vertical direction falls in the cavity of the metal anti-cracking net, and the nails are anchored into the ground through the depressions of the anchor plate by a gas gun.

[0006] After adopting the above structure, the utility model provides a quick anchoring device for metal anti-cracking net on the pavement, which has the following advantages: when the metal anti-cracking net is anchoring, the anchoring sheet is covered on the twisted part, the two first bevels and the two second bevels of the metal anti-cracking net, and the nails are driven into the ground through the depressions using a gas gun, and the metal anti-cracking net is anchored by the nails in conjunction with the anchoring sheet, which improves the anchoring efficiency and reduces the intensity of the work, and the position of the anchoring sheet is limited by the limiting piece on the lower end face of the anchoring sheet, and the depression is used as the anchoring reference, so that the nails can be accurately shot into the ground through the anchoring sheet, further improving the anchoring efficiency and reducing the intensity of the work.

[0007] As an improvement, the limiting member includes two first protrusions, the two first protrusions are connected to the lower end surface of the anchor plate, the two first protrusions are respectively parallel to the two first oblique sides and are respectively used to abut against the upper sides of the two first oblique sides or are respectively parallel to the two second oblique sides and are respectively used to abut against the lower sides of the two second oblique sides; with this structure, the position of the anchor plate on the metal crack net is more accurate through the limiting of the two first protrusions, further improving the anchoring efficiency and reducing the working intensity.

[0008] As an improvement, the lower end surface of each first protrusion is serrated and used to abut against the ground; adopting this structure, the stability of the connection between the anchor plate and the ground is improved, and the anchoring of the metal anti-cracking net is also made more reliable.

[0009] As an improvement, two second protrusions are connected to the upper end surface of the anchor plate, and the two second protrusions correspond one-to-one to the two first protrusions. With this structure, the two second protrusions serve as the reference for the two first protrusions, which makes it easier to accurately and conveniently make the first protrusions collide with the corresponding beveled edges when placing the anchor plate, thereby further improving the anchoring efficiency and reducing the work intensity.

[0010] As an improvement, the upper end surface of each second protrusion is serrated; with this structure, when asphalt concrete is laid above the metal anti-cracking net, the upper end surface of the second protrusion can be more stably combined with the asphalt concrete.

[0011] As an improvement, a plurality of first serrated blocks are distributed on the upper end surface of the anchoring plate; with this structure, when asphalt concrete is laid above the metal anti-cracking net, the serrated blocks enable the anchoring plate to be more stably combined with the asphalt concrete.

[0012] As an improvement, the anchor plate is rectangular, and at least two corners of the anchor plate form a thin portion, the thickness of the thin portion is less than the thickness of the anchor plate, and each thin portion is provided with a depression; with this structure, when a nail is driven into the depression by a gas gun, the thin portion is more easily deformed downward relative to the anchor plate, so that the thin portion can be close to the metal anti-cracking net and the ground, thereby improving the stability of the metal anti-cracking net anchoring.

[0013] As an improvement, a plurality of second serrated blocks for abutting against the ground are distributed on the lower end surface of each thin portion; with this structure, after the thin portion is deformed downward, the second serrated blocks abut against the ground to improve the stability of the anchoring.
